Hand-drawn lettering

Hello

Ive recently just started hand drawing certain aspects of my posters, and am quite enjoying some of the outcomes (I think somewhere along the line of using my computer too much, i forgot i could actually DRAW!) but i need a bit of help...

Does anyone know of any online lettering tutorials that are worth a look?

Ive quite got into lettering, but as its not something ive done for awhile, Im a bit rusty and all my letters keep coming out the same.
